High-quality human data for AI training, evaluation, and research
Filter participants by detailed demographic, professional, and behavioural criteria and reach narrow or representative samples rather than a generic crowd.
Collect human preference data for model fine-tuning, run safety evaluations and red-teaming, and use a feedback API to plug humans into automated pipelines.
Attention checks, honesty screening, and approval workflows help filter out careless or fraudulent responses before you analyse results.
Publish a study and begin collecting responses quickly, with tooling that supports screening, quotas, and longitudinal designs.
Options flow, dark pools and dealer gamma with an AI analyst built in
Reads the full OPRA options tape in real time so you can see net premium and flow direction per stock and across the whole market.
Ranks dark pool block prints against each stock's own yearly activity to surface unusually large or unusual off-exchange trades.
Models dealer gamma, delta, vanna and charm for roughly 2,500 stocks on a five-minute refresh cycle to gauge hedging pressure.
An AI analyst pulls the market data itself to answer questions, plus flow-signal pattern studies, backtesting and an API/MCP server on higher tiers.
